Question

a train travelling at a uniform speed for 360km would have taken 48 minutes less to ravel the same distance if its speed were 5 km/hr mote find orignal speed of train

Answer 1

Let the speed of train be x km/hrDistance to be travelled  = 360kmWe know that, Time take by the train intially = If the speed was increased by 5km/hrTime taken by train = Difference in the time taken is 48 minutes,x2+5x -2250 = 0(x+50)(x-45)Speed = 45 km/hr as speed cannot be negativehope this helps you..............

Answer 2

Let the speed of train be x km/hrDistance to be travelled  = 360kmWe know that, Time take by the train intially = If the speed was increased by 5km/hrTime taken by train = Difference in the time taken is 48 minutes,x^2+5x -2250 = 0(x+50)(x-45)Speed = 45 km/hr as speed cannot be negative
